Chroot the users to a common sftp root instead of their home directory
("/usr/sftpusers/" for example). You will have to tell them to cd to
"/myusername" to write to their private directory, or "/Drop" to upload to
the common dropbox directory.

Another solution might be to leave everyone chrooted in their home
directories, create a /Drop directory in everyone's home dir, and have a
crom job that runs every 5 minutes or so that moves files in
/usr/sftpusers/*/Drop/ that are older than 5 minutes into your other dropbox
directory, where you can process them at your leisure. This won't work if
they are supposed to be able to download files that other users have
uploaded, though.
